Description
Technical field
The present invention relates to a kind of simulation test bench of automobile cooling system.
Background technology
It is to analyze each mutual disturbed condition in parts overlap joint back that automobile cooling system is tested its fundamental purpose, and distribution situations such as comprehensive evaluation engine-cooling system water resistance, flow system flow and pressure are for car load cooling system exploitation coupling provides foundation and index.Existing automobile cooling system test mainly contains following several mode: one, block testing stand cooling system test, its advantage can accurately harmonize arbitrarily engine load and speed conditions, but lacking the simulation car load arranges, in case behind the cooling system change annex (as water tank, pipeline, warm braw core body etc.), it is higher to carry out the engine rig test cost again, and the day-to-day test operability is relatively poor; Two, main at present indoor environment simulation and the outdoor actual road test of relying on of car load cooling system test, because being subjected to the car load nacelle arranges and space constraint, cause daily cooling system pilot project imperfection, only the energy measurement engine is in the temperature of engine water outlet, water inflow of the engine, engine motor oil under the part load condition; Three, the test of cooling system parts is mainly finished coherent detection by supplier at present, and only at the endurancing as parts such as electronic fan, water tanks, pilot project is simple relatively and lack systemic.
Summary of the invention
Technical matters to be solved by this invention is, overcome the above-mentioned defective that existing automobile cooling system test exists, a kind of simulation test bench of automobile cooling system is provided, testing table of the present invention combines the advantage of above-mentioned engine rig test and the test of car load cooling system, make full use of stand of the present invention and carry the required various parts of Full Vehicle System, collect operating characteristic such as each annex flow of engine-cooling system and pressure, at the beginning of product development, mid-term, cooling system coupling and the data aggregation of competition vehicle cooling system provided accurate, effectively, testing tool easily; Heat exchange amount when also can be used for quantitative test such as heating test and cooling system thermocycling in addition, association areas such as part of cooling system performance test and durability test.
The invention provides a kind of cooling system simulation test stand, comprise motor, gear train, the well heater assembly, water-cooled engine, engine liquid pump assembly, vehicle cooling system a plurality of sensors of unifying, motor drives the engine flywheel dish by gear train, make the engine flywheel dish drive the engine water pump running by the engine body gearing, the well heater assembly is installed in the water-cooled engine body, be used for the intrinsic anti freezing solution of heated engine, automobile cooling system is connected with engine liquid pump assembly with water-cooled engine by pipeline, anti freezing solution can be at engine, circulation in engine liquid pump assembly and the automobile cooling system, a plurality of sensors are used to detect the required data of test.
Motor is a variable-frequency motor; The motor speed control accuracy is: ± 10r/min.
Gear train is belt gear or chain drive or transmission shaft transmission.
It is the rated speed of engine that the maximum speed of motor passes through after the gear train speed change.
The heating power of well heater assembly is adjustable.
Automobile cooling system comprises car radiator assembly, expansion tank assembly and Water heating for vehicle formula assembly.
The influence of simulation test bench of automobile cooling system of the present invention between can each annex of analysis of system, can detect more intuitively as discharge and pressure distribution in the warm braw core body, thereby can effectively avoid the blindness of appurtenances flow matches (carrying different vehicle annexes as a engine) in product development process at present if rely on engine pedestal fully then the day-to-day test poor operability; The quality to the buying exemplar that can be convenient is spot-check and is controlled, and prevents quality problems in the production run; Convenient each the annex matching database of competition vehicle cooling system of setting up is for the exploitation of vehicle provides empirical value; For example: in car load 40km/h 12% operating condition of test, detect engine and go out 105 ℃ of water temperatures, 100 ℃ of water inflow of the engine temperature, engine speed 2500r/min.Can carry out digital simulation: engine speed 2500r/min in conjunction with the cooling system testing table, measure each annex flow situation during 105 ℃ of engine outlet water temperatures, auxiliary complete vehicle test calculates car load upper water box heat dissipation capacity, thereby more objectively analyzes each annex performance of cooling system.
